A Predictive Method of LCC-HVDC Continuous Commutation Failure Based on Threshold Commutation Voltage Under Grid Fault

IEEE Transactions on Power Systems, 2021
Line-commutated converter based high-voltage direct-current (LCC-HVDC) has been extensively applied in power system. LCC-HVDC is prone to continuous commutation failure (CCF), which consequently causes numerous active and reactive impacts, thereby ...

Integrated LCC-LCC Topology for WPT System With CC Output Regarding Air Gap and Load Variations

IEEE transactions on power electronics
In magnetic coupling wireless power transfer systems, air gap and load changes are very common. Due to the presence of ferrite cores, changes in the air gap can lead to variations in coil parameters (mutual inductance and self-inductances), particularly ...
